Product Description
Wollastonite powder has needle-like shape, high whiteness and unique physical and chemical properties. It is widely used in ceramics, paints, coatings, plastics, rubber, chemicals, papermaking, welding rods, metallurgical protective slag, asbestos substitutes, etc. Adding an appropriate amount of wollastonite powder to ceramic raw materials can greatly reduce the firing temperature, shorten the firing time, achieve low-temperature rapid firing, save a lot of fuel, reduce product costs, reduce cracks and warping, increase gloss, and improve green body strength.

Advantages
1. In the plastic industry, wollastonite powder not only acts as a filler, but can also partially replace asbestos and glass fiber as a reinforcing material.
2. In the rubber industry, natural wollastonite powder has a special needle-like structure, is white, non-toxic, and ultra-finely ground. After surface modification, it is an ideal filler for rubber, which can not only reduce the production cost of rubber products, but also improve the mechanical properties of rubber.
3. In the coating industry, wollastonite powder is used as a filler for paints and coatings to improve the physical and chemical properties, durability and weather resistance of the products, reduce the glossiness of the paint, enhance the expansion capacity of the coating, reduce cracks, reduce oil absorption, and enhance corrosion resistance. Needle-shaped wollastonite powder has good flatness, high color coverage, uniform distribution, and UV resistance. It is widely used in interior wall coatings, exterior wall coatings, special coatings and latex paints.
4. In the papermaking industry, wollastonite powder can be used as filler and plant fiber.
Compounded into papermaking composite fiber, replacing part of plant fiber. Reduce wood pulp usage, reduce costs, improve paper product performance, increase paper product smoothness and opacity, and improve paper uniformity
Products can eliminate paper static electricity, reduce paper shrinkage, improve printing suitability, and reduce factory pollution emissions
During fiber pulping process.
